C'mon now, credit where credit is due:
Roger A. Pielke Jr. is an American political scientist and professor, and was the director of the Sports Governance Center within the Department of Athletics at the Center for Science and Technology Policy Research at the University of Colorado Boulder.
But yes, a long time denialist amd one frequently steadfastly wrong in the face of evidence independantly confirmed by multiple third parties of standing.
He got that from his father who was also an AGW denialist (a climate change believer, but a denier that humans play any meaningful role), albeit one with more relevant credentuals:
Roger A. Pielke Sr. is an American meteorologist with interests in climate variability and climate change, environmental vulnerability, numerical modeling, atmospheric dynamics, land/ocean – atmosphere interactions, and large eddy/turbulent boundary layer modeling.
FWiW it is universally acknowledged that Jnr. does have considerable expertise and knowledge in the field of water polo.
